Properties Of Soil

Agricultural practices that improve agricultural sustainability are needed particularly for brown luvic soil. Soil enzyme activities can provide information on how soil management is affecting the processes in soil such as decomposition and nutrient cycling. Soil enzyme activities (actual and potential dehydrogenase, catalase, acid and alkaline phosphatase) were determined in the 0–10, 10–20, and 20–30 cm layers of a brown luvic soil submitted to a complex fertilization experiment with different types of green manure. It was found that each activity decreased with increasing sampling depth. It should be emphasized that green-manuring of maize led to a significant increase in each of the five enzymatic activities determined. The enzymatic indicators of soil quality calculated from the values of enzymatic activities showed the order: lupinus + rape + oat > lupinus > vetch + oat + ryegrass > lupinus + oat + vetch > unfertilized plot. This order means that by determination of enzymatic activities valuable information can be obtained regarding fertility status of soils. There were significant correlations of soil enzyme activities with physical properties.

Phosphatase Activities

Actual and potential dehydrogenase and catalase and phosphatase activities were determined in the 0–20–, 20–40– and 40–60–cm layers of a brown luvic soil submitted to a complex tillage and crop rotation experiment. The soil under maize or wheat was more enzyme-active in the 6– than in the 2–crop rotation. In the 2–crop rotation, higher enzymatic activities were registered under wheat than under maize. In the 6–crop rotation, the enzymatic indicators of soil quality decreased, depending on the nature of crops and kind of fertilisers (mineral NP or farmyard manure), in the following order: farmyard-manured maize > minerally fertilised (m.f.) soybean > m.f. wheat > m.f. maize (plot 4) > m.f. maize (plot 1) > m.f. clover.

Taked an repaired completed slope - Vegetation-Growing Concrete Gunning (VGCG) slope for the experimental plot to measured indicators could evaluate the physical, chemical and biological properties.It showed that there were significantly difference in SBD, PH, SOM, AN. AP. AP and AK in different seasons, but no law. And there were significantly difference in soil enzyme activities except catalase in different seasons. Soil enzyme activities were highest in summer, lowest in winter except catalase. It showed that enzyme activitiy roses at first in the lower from spring to winter in one year. It proved that there were ruleless in seasonal change of the soil physical and chemical properties and there was a certain rule in seasonal change of the soil biological properties of the VGCG slope in one year.

The Relationship

In this paper, simulated experiments were performed in pots by using soil materials in different conditions of film remnant. Based on the research on soil microorganism quantity trends of soil enzyme activities were analyzed systematically: soil without film remnant, soil with film remnant for 5, 10, 15 and 20 years. By analyzing crop progress, the relationship with soil material was studied, in order to provide scientific basis for the variation laws between different conditions of film remnant and the activity of soil enzyme.
